Single Zener Diodes Procurement Notes

Verify the authenticity of the component by checking for the cathode band marking and type number. Ensure the ordering suffix matches the required packaging format, such as tape and reel or bulk. Confirm RoHS compliance status and lead-free finish specifications against the latest manufacturer documentation before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 56 V breakdown voltage is required in an axial through-hole configuration. Consider the 500 mW power rating and thermal derating requirements above 50°C during circuit design. Evaluate the positive temperature coefficient to ensure stability across the intended operating temperature range.

Single Zener Diodes Part Context

This part belongs to the 1N5221B through 1N5267B series of 500 mW Zener diodes manufactured by Micro Commercial Components. The series covers a wide voltage range from 2.4 V to 75 V, all sharing the same DO-35 glass package and general electrical construction standards defined in the official datasheet.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering the 1N5263B designation in a DO-35 package. Verify that substitute parts match the 56 V nominal voltage, 5% tolerance, and 500 mW power dissipation ratings to maintain circuit performance integrity.
